[flashrom] jmicron SATA/IDE flashing of option rom

[Rudolf Marek]

Hi,

I own JMB363 SATA/IDE. I figured it out how to flash it with a flashrom. It has the parallel flash
which is 512KiB (SST39VF040), but the memory BAR where the flash is visible is only 64KiB.

How flashrom deals with such programmers? It looks like I just need to mask the address bits not to get out of the BAR.
Maybe I need to use "layout" feature?

Has someone else the jmicron SATA/IDE controller? I guess we could support similar controllers.

Thanks
Rudolf
